Seasonal and Climate Advice
The short answer
Southern California is six climates, not one, and a coach stored in Palm Desert fails differently than the same coach stored in Newport Beach. These articles cover low desert heat, coastal salt air, Santa Ana wind damage, high desert hail and freeze, and who in this region actually needs to winterize.

About this category
An RV parked in Indio and an identical RV parked in Oceanside will need different repairs at different intervals, and neither owner is doing anything wrong. The Indio coach is losing its roof membrane and its adhesive bond to sustained heat above 115 degrees. The Oceanside coach is losing fasteners and gelcoat to salt that deposits every night and never washes off. Same unit, same year, two completely different maintenance calendars. That is the point of this category. Generic seasonal advice written for the whole country is close to worthless here, because the drive from Newport Beach to Palm Desert crosses three climate bands in two hours. These articles are organized by band, name the cities in each, and give the failure modes we actually see arrive from those places along with the timing that heads them off.

Winterizing an RV in Southern California: Who Actually Needs It
Coastal Orange County almost never needs winterization. Big Bear, Wrightwood and the high desert do. Here is the temperature rule that decides it.
